技術說明

因意外事件或病變引起的骨折損傷，常以交鎖式骨髓腔內鋼釘幫助骨頭自然癒合。然而，在執行遠端鎖定螺絲(distal screw)的植入，若由經驗較不足的醫師執行，往往需要花費數倍以上的時間。遠端固定孔螺絲鎖定通常是透過X光透視導引來完成。但為了避免多餘的輻射吸收，一些採用導引器執行遠端螺孔定位的方法與裝置被陸續研發出來。但髓內釘在置入髓腔的過程中會因為受到外力衝擊產生扭曲形變，可能造成無法順利鎖定螺絲的問題。 初步的實驗結果證實(W. Chu, Injury 2009)，使用可見光光源（或波長較長的紅外光）置入骨髓腔內，用肉眼可以從體外清楚的觀察到髓腔內鋼釘固定孔的位置，大幅減少執行遠端鎖定螺絲的時間，卻沒有輻射劑量吸收的副作用。對於病人及執行手術的醫療人員（醫師，護士等）都是一大福音，預期將很容易獲得病人與醫師的認同採用。 For decades, intra-medullary nailing has been the most commonly used technique when treating patients with lower limbs fractures. During the operation, a crucial but tedious step is to locate the distal interlocking screw holes where it may take long time to deal with. To date, this procedure has been performed either using fluoroscopy or with the aid of a specially designed target-aiming device. But there are still several defects for the above two methods like radiation hazards, time-consuming, or lack of efficiency and efficacy. Our preliminary experiment result shows that, with the visible light source inserted into the medullary bone cavity to detect the distal interlocking screw holes, the light penetrates out of the bone surface, revealing the position of the screw hole and it allows the subsequent drilling and placing of the interlocking screw to be more efficient and accurate without fluoroscopy.
